The heating and cooling capacities of the unit should be greater than or equal to the design heating and cooling loads of the area to be conditioned. The loads should be calculated by an approved method or in accordance with ASHRAE Guide or Manual J - Load Calculations published by the Air Conditioning Contractors of America. Obtain from: American National Standards Institute 25 West 43rd Street, 4th Floor New York, NY 10036

System design and installation should also, where applicable, follow information presented in accepted industry guides such as the ASHRAE Handbooks. The manufacturer assumes no responsibility for equipment installed in violation of any code or regulation. The mechanical installation of the packaged roof top units consists of making final connections between the unit and building services; supply and return duct connections; and drain connections (if required). The internal systems of the unit are completely factory- installed and tested prior to shipment.

WHEN UNIT IS SUSPENDED, BOARDS AND SHIPPING BRACE WILL DROP WHEN SCREWS ARE REMOVED. TO PREVENT PERSONAL INJURY, STAND CLEAR. REMOVE FORK HOLE BRACKETS, BOARDS AND SHIPPING BRACE FROM BOTTOM OF UNIT BEFORE PLACING UNIT ONTO CURB.

Before installing this unit on a roof curb: 1. Remove wooden struts per installation instructions. These are the struts that are located in the fork holes and are used to protect the unit from damage while lifting with forks. 2. Locate and remove the twelve (12) screws that attach the shipping brace to the side rails. There will be six (6) screws on each side of the unit and they are in a diagonal pattern.

If flame is not established within the seven (7) second trial for ignition, the gas valve is deenerigized, 15 second inter-purge cycle is completed, and ignition is reattempted. The control will repeat this routine three times if a measurable combustion is not established. The control will then shut off the induced draft blower and go into a lockout state.
